The long-wheelbase versions of BMW's flagship limousine, the 7-Series, isn't on the top of our list when it comes to extensive performance modifications, but if that's your thing, Germany's Tuningwerk has you covered. The company starts out with a standard BMW 750Li that is powered by a 4.4-liter turbocharged V8 pushing out 407HP and 600Nm (443 lb-ft) of peak torque, offering buyers two options.
The first package called the GT Edition and it lifts output to 530HP and 740Nm (546 lb-ft), allowing the German limo to accelerate from zero to 100km/h (62mph) in 4.2 seconds and reach an unrestricted top speed of 310 km/h (193mph).
For those looking for the ultimate power boost there's the RS Edition that comes with 720-horses and 1,090Nm (804 lb-ft) for a 0-100km/h sprint time of just 3.5 seconds and a top speed of 350km/h (218mph).
Other modifications include a lightweight CarbonCeramic brake system, a new sport exhaust, a subtle aero package with front and rear aprons, side skirts and a boot lid spoiler, 20-inch black wheels shod in Pirelli P-Zero tires and a carbon-fibre engine cover.
Pricing starts from €169,800 (US$230,800) for the 530HP GT Edition and from €198,000 (US$269,000) for the 720HP RS Edition.
